My speed-passer. His role is simple for my team, pass to marowak with an agility and if thats not open I can try to pass to a dedent speed pokemon to outrun everyhting in the game. HP Grass is cool for Swampy that shows in adv a lot. Thunderbolt is always a threat off zappy and can be that last strike I need.

This was hard to decide on. right now atm i have fire blast and lum for skarm and screw-uppers. however if i run Sub and liechi I can pull of 2 DDs and a liechi boost and sweep everything but skarm. ... dilemma dilemma. I need help here

Curselax after 6 curses 2HKOS forretress...thats cool. anyway rest kills me when i use it because now im either missing a way to deal wih steels or i miss a way to kill ghosts. i liek EQ and shaodw ball. Also helps with big ice weak

Except this isn't the team blaze server, so Slowbro doesn't get Slack Off.

Liechi Berry Gengar seems a little gimmicky to me, because the chances that you get hit once are very high, and if you try to Explode it can easily be predicted and you end up doing nothing to say, Skarmory, or another Gengar. Go with Leftovers.

On Dragonite, again, I would go with regular Leftovers over the berry, because you don't really need +4 Attack to sweep the team, and it is really easy to have something with Ice Beam that won't die from a 1 DD HP Flying.

You'll have to break your RBY-only restriction, because Steel Pokemon seems to help a whole bunch for your team's defenses. Registeel with Thunder, Thunder Wave, Counter, Earthquake / Explosion perhaps. Thunder spoils Skarmory's attempt to stack Spikes; T-Wave helps both Snorlax and Slowbro in the offensive, as well as crippling threatening Sweepers; Counter EQs / Curselax's moves; and Explosion / Earthquake to break Ttar, Jirachi, and Raikou's sub. Possibly over Dragonite, since Dragonite can't sweep in a team that lacks fundamental coverage to popular Pokemon anyways, and doesn't gain much from Registeel's support.

Slowbro needs Ice beam if it wants to be a functional water pokemon, and Ice provides a reliable offense against Salamence, Celebi and Zapdos. Although, Fire Blast seems very appealing for dealing with Steels and such, Surf is necessary to provide better coverage.

Eh, I dunno how valuable Double-Edge is, so you could try Swords Dance here. Setting up one after a Speed-pass is basically scrapped a team. I also agree on the Sleep-Talking Snorlax, as you need some sort of cushion for hits and such.
